Abstract: A brake system includes a brake master cylinder assembly that is configured to connect to a brake pedal, and includes a master cylinder housing and a master cylinder piston being moveable inside the master cylinder housing and defining a compression chamber inside the master cylinder housing. A displacement sensor is mounted on the brake master cylinder assembly. An electro-hydraulic assembly is disposed separately from the brake master cylinder assembly, the electro-hydraulic assembly and the brake master cylinder assembly are connected by a connecting oil pipe and are in communication by a brake fluid in the connecting oil pipe, and the electro-hydraulic assembly is configured to connect to a wheel brake. A controller is connected to the displacement sensor and the electro-hydraulic assembly, and controls, according to an action of the brake pedal or a brake command, the electro-hydraulic assembly to output the brake fluid to the wheel brake.
